[57] [Abstract] [Problem] A small-scale on-site construction can be easily performed even at a repair site in a low-temperature or wet state, and the curing after the construction is fast, and the cured material has high strength, abrasion resistance, and durability. Provided is a bituminous composition for road surface repair capable of obtaining a smooth surface finish. An aggregate component (a) containing an aggregate having a specific particle size, a cement and / or lime (b) containing 4% (%) or less of the aggregate component, a bitumen emulsion (c), and a polyisocyanate and a molecule. A composition comprising a compound containing two or more active hydrogens and a urethane prepolymer having terminal isocyanate groups (d) obtained by reacting N-hydroxyalkyloxazolidine has solved the above-mentioned problem. |
